SYSTEM OF DBAFTING LOCOMOTIVES IN ROUNDHOUSEE.

Application filed September 14, 1925. serial no. 56,118.

This invention relates-to drafting of locomotives in roundhouses during the firing. up period, but it is capable of general use particularly certain parts of it.

The principal objects of the invention are to eliminate the usual steam pipe with which roundhouses are now. provlded; to substitute for it electrical mechanism which will be shut off automatically when the blowers are removed, thus saving power; to provide means for drafting locomotives in the different stalls of a roundhouse or any other place where locomotives vmaybe drafted such as repair sheds, railroad yards, sidings, etc. by a portable blower to e attached to or placed on the stack of a locomotive and to discharge the ases of combustion into the smoke jac or uptake through the roof of the roundhouse or into a stack or chimney, or directly into the open atmosphere; to provide a blower driven by a motor to handle the gases of combustion and to provide means for cooling the motor during its operation; to provide means for quickly transferring this blower from one locomotive to another; to provide the blower with a suitable support to place it on the stack of the locomotive regardless of the position of the locomotive.

in relation to the smoke jack or-gas uptake; to provide means for connecting the blower with the top of the smoke jack regardless of the tilting of the locomotive; to provide means for automatically starting-and stopping the blower when it is placed within close proximity of the locomotive stack or taken away from the locomotive stack; to provide supporting means for the blower in case the locomotive should be backed out of the roundhouse while the blower is on the stack of the locomotive; to provide means to protect the motor against the gases of combustion and also against any discharge by the steam of the locomotive steam jet b ower if this should be turned on while the blower is on the stack; to provide means for fittin the blower on different sizes and heights 0 locomotive stacks; and to provide automatic means for lubricating the bearin s of the blower.

Every time the boiler of a locomotive is cleaned and inspected, which is-done at least once a month, a new fire must be started in Fig. 21 is an enlarged sectional view onthe connection must be made through a flex ible hose or steam pipes with fiexible couplin s. This method .is very costl and cum ersome. The advanta es of a lower system are fully appreciate but heretofore blower systems have always been of a. sta-' tionary nature, the stack being connected by flexible or telescoping pipes to the blower intake. The blower then discharges the gases of combustion, or the air induced, through a chimney. This system has been found very costly to maintain, cumbersome in operation, and tending to a waste of power on account of the tendency of the operator to leave the blower intakes open, thereby using needlessly much power.

With my system I provide a small motor driven blower which takes care of one locosuch blowers may be used side by side or I motive at a time, but may be used in any one stall of the roundhouse. A number of widely scattered over the roundhouse thereb giving the utmost flexibility of operation, Fin this purpose 'I provide a monorail s stem from one end of the roundhouse to the other, with a spur leading to each stall of the roundhouse, these spurs being connected to the main fail by two way switches; Instead of'using a monorail with spurs each stall or draftin space may, of course, be

i provided indivi ually with an independent rail or track.

In Fig. 1 I have shown part of a roundhouse having a wall 111 with a monorail system having a number of stalls 112 each with a smoke 'ack'113 as usual, I-beams 114 constituting t e main rail arallel to the wall and there are a series o spurs 115 and two way switches or pivoted track sections 116 of usual construction. These switches are each operated by two chains 110 hanging down. Each spur runs outside the smoke jack out of the path of the gases which rise from the smoke stack when the en 'ne is put under it. This adds to the durabi ity of the rails as they are not in the direct path of the corrosive gases.

Each spur 115, has brackets 58 which support a switch box 59. The wires 69 (Fig. 3) of the motor end in contactors 61 which engage with flat conductors 63 of the switch box 59.. By means of a chain 62 rating a sprocket connected with-gearing o 6 a. geared trolley 55 is moved along the track carrying the blower. To allow it to 7 pass around the curve and through the two way switch the switch of the trolley is loosely fitted on the opposite flanges of the I-beam. This play ;may prevent the contactors 61 from engag ng properly with the conductors 63. To take this play away the I-beam is provided with a filler 118 within the operatin zone so thatthe opposite converging wheels 119 of the trolley'55 have no side play. This filler 118 has a slant 120 at the entrance point so as to facilitate the proper placing of the trolley.

The blower is carried .by trunnions 52 on a fork 51 counterweighted at 57 and supported on a swivel joint 53 b a chain 54 from the trolley 55 so that the lower can be raised and lowered. Chains 56 limit the downward travel of the blower about the pivot, the blower being slightly heavier than the counterweight 57. As soon as the contactors disengage from the wires 63 the motor stops. Therefore, the blower will always be in operation when it is within the normal operating zone, that is, anywhere below the smoke jack, the reason for which will be explained later.

By pulling straight downward on a chain 66 t e blower will be raised, and by letting this chain go the blower will be lowered thus taking care of different heights of stacks. By pulling on the chain sideways the blower will describe the arc of a circle, pivoting about the supporting chain 54, therebyv allowing the blower to take up any position within this are and lowering it on the smoke stack of the locomotive whether this is located right in the center of the smoke jack or on eitherside of. it.

Through the arms of the supportingfork 51 (Fig. 10) extends the pivot bolt 68 with a bushing 69 on which is mounted the inner race of a self-aligning bearing 7 O. The outer race of this bearing is located in a housing 71 covered by an enclosure 72. The hous-' ing 71 has a vertical eye-bolt 73 to which is fastened the supporting chain .54 so that there is a slight oscillating motion around point 74 in the center of the fork 51. His necessary that this motion be about this point to enable the relative pro ortions in the weights of the blower and t e counterweight to be maintained. This motion is sufficient totake care of any dis-alig ment of the stack so that the blower Wlll rest snugly on the stack regardless of its position even if the locomotiveis tilted materially out of its normal u right position.

The blower casing 50 ig.7) is formed in'two pieces, to the upper of which is bolted a spider 81, the hub 82 of which forms the upper end cap and bearing housing of the motor. This end cap has cored slots 83 and an end shield 84 which forms with the hub 82 a continuation of the cored slots 83.- Leading to the cored slots 83 is an annular air chamber 85 formed by the motor housng 86 and motor cover 87 enclosing the entire. motor. To this air chamber 85 lead one or more" radial pi es 88 from the outside of the lower part 0 the blower casing 50 which is bolted to the upper part by four bolts 90. The air therefore, passing through the tubes 88, enters the annular airichamber 85, then passes through annular slots 83 into the passage between the housing 82 and the shield 811. The air is drawn through this passageway by the suction created byv the fan 91. The air, however, is also drawn through the motor itself by the action of fan 91, assisted'byasnialler fan 92 on the same vertical shaft 103 which discharges V the air into the hollow hub of the fan 91 and out throu h'holes 93, thereby cooling the inside of-t e hub so that very little or no heat is transmitted to thejshaft by the fanblades. 'A throw rin 94 prevents any" dirt from falling down t rough the holes 5 93 or any rain or water of condensation from entering similarly. We have seen' that vthe blower is in motion when in proximity of the stack and will remain in motion until taken out of the operatin zone. Therefore, if any steam should be ischarged through the stack it cannot reach the motor because of the provisions just described.

This blower has two 'ball bearings 101, the oilin of which is accomplished as follows: Oi is poured into a receptacle 95 until it overflows through a hole having a plug 96 which is then secured in place. 'A pipev 97 leadsfrom the receptacle to the oil chamber 102 .of the motor and this oil chamber will be filled approximately to the top. of. the .lower ball bearin A screw nut 98,- rotating with the sha t 103, pum s the oil upward through a hole 104 throng the center of the shaft, putting the oil in this hole under pressure. Above each ball bearing is an outlet 105 from this hole and the oil flowi through the lower outlet will pass throng the ball bearin and immediately into the oil reservoir, w ile the oil passing through the upper hole flows through the ball bearing into a chamber 99 then out throu h a pipe 100 back to receptacle 95. The ow'of oil will continue as lon as the motor is in oper tion. The pipe. 9% passes through one of the air inlets 88 and therefore is kept cool, and thepi e 100 passes through erv .pipe 106 whic communicates with Y the air passage 83 for the same pur A relief over-flow 107 is provided fort supper anot bearing. y

With this construction, the steampipes with, which .froundhousesfare ordin'arily equipped for the purpose of. drafting the locomotives. are entirely eliminated. This also eliminates. the expense of installation and upkeep of these pipes and their supply from the boilers; Automatic means is provided for shutting off the power whenever 'inattentionof that kind. The portable blower is" easilyfitted to the stack of the locomotive even if the stack is not centrally located under the jack or if it is tilted to one side. The blower can be carried quickly from one locomotive to-another and is provided with means for protecting the motor against the heat of the gases of combustion and steam from the steam jet blower if that is turned on. Automatic means is provided for lubricating the bearings of the blower and means for cooling the motor as it oper-.

ates. This is a material improvement over the blower systems that have been installed heretofore because the blower is portable and no flexible or-telescoping" pipes have to be used in connection with it that may be left open, thus wasting ower.

F ig. 11 shows a mo ified layout of the monorail system, 'in .which the spur 125 is hinged at 126 so that the blower may be moved slightly to the left or right to take care of any tilting of the locomotive stack. a

The free end rests and slides on a horizontal bar 124. In this case the track normally moves directly under the smoke jack 113.

This has thedisadvantage that the I-beam is in the direct path of the gases of""com Y bustion whichare highly corrosive. I have shown in Figs. 12 and 13 how the rail 125 can be pivoted on the stud 126. The pivot stud is mounted on a plate 123'secured to. the bottom of a stationary rail 127. Overlapping plates 128 and 129 are secured to the tops of the rails125 and 127.

In this case the rails and trolley may be the same as above described but the blower casing is considerably modified asshown in Figs. 14, 15 and 16. The intake 130, in

llb

stead of being fixed to the blower casing, telescopes 'with'one. or more sections or collars 131. These sections are moved up and down by two chains or ropes 132 running over quadrants 133, one of the] quadrants having an arm 134 with a chain135 to operate itfrom the floor. Therefore, instead of moving the blowerupand down, only the intake is moved up, and down and no hoist is necessary. The blower is suspended by blower-casing is suspended by chains 8 and a joke 8 fulcrumed at 8 in a lug" 8 of the a link 136 pivotally depending from the "trolley c In the form shown in Figs. Hand 18 the conical intake which rests on the locomotive stack, the blower being moved up and 15 down by the operating chain 16 of the hoist. By operating the chain 17 of the geared trolley the blower is moved in or out of the ac a c l Figs. 19 to 22 show the blower witha screw hoist instead of a chain hoist, as previously described. The blower is suspended from the screw rod 20, fulcrumed at 21 so that it can swing slightly out of its normal position in order to set squarely on the locomotive stack if the locomotive should be tipped to one side. Bracket 22 whichis fastened to the blower outlet, has a fork 23, the arms of which are guided by the flat sides of the housing 24 of the screw hoist so that the blower and the hoist rod 25 are prevented from turning around the center of the rod.

The blower. itselfconsists' of a housing 3 having an intake elbow 31 provided with a flared inlet 32. To. the upper part of the blower housing is bolted a fan casi'n 33 with a hub 34 containing a'bearing-bus ing 35 through which passes the shaft 36. The

- bushing 35 is provided with'prongs or ribs on the outside so that air passages 37 are'.

formed between the hub 34 and the bushing. The hub 34 is fastened to the casing 33 by means of ribs 34 and between these ribs are gaps 34 which are closed by covers and thus constitute air passages. The inlet to the air passages 37 is closed by a pipe and the inlet to the air passages 34" is closed by a flat plate-'41 and a pipe 42, This forms an air passage'bet-ween the pipes 40 and 42 which communicates with atmosphere outside of the blower. An air passage is also formed between the pi e '40 and the shaft 36 com,-

" municating wit the passages '37 and opening tor is located out of the up to the motor casing. By the action of the fan 38 air is-d'ra'wn from the outside betweenthe pipes 40 and 42 and also through the motor and around the shaft. At the extreme end of theshaft isj the'fan 38 discharging the gases into the blower outlet 39. I On the other end of the housing, 30 is bolted vj-the motor frameconsisting of a cap 43.,

shell 44, and cap 45, the'latter containing the other bearing of the blower. Thusthemoath of the heated of combustion. e lubrication. of

gases bearing is furnished by an ordinary this grease pipe for the u per bearing is located inside of a sleeve WlllCh is screwed into the A guard 46 protects These doors are for the purpose of letting cold air into the blower housing if the blower should be allowed to remain on a stack not in operation, thereb reducing the temperature of the gases an consequently the heat to which the bearing 55 is subjected. The motor is provided with long wires for plugging in {:Ihe motor at, a. convenient place for each sta In the form shown in Figs. 23 to 25 the blower 5O sup orted in the way shown in the first three figures or in an other desired way, is adapted to be inserte in the flaring conical inlet 140 at'the bottom of a flexible hose 141 so that the hose can receive the gases drawn up through the blower. The

ring 142 which is held up by chains 143 running over plulleys144 and held up by a counterweig t 145 preferably in the orm of it ring almost heavy enough to pull up the ose. Y

The parts just above described are located in the chimney 146 and no smoke jack is required although the can be located in one if desired. On the .inlet 140' are attached The hose 141 can be formed l three or more chains 147 running to pulleys 148 in different directions and hanging down so that the can be operated to move the hose aroun with the blower'on it, or without. it, but ordinarily when the blower is on it the blowerwill be' manipulated as in the preferred form shown. The blower can be put on the stack of a locomotive as shown in full lines-in Fig. 23 and if the locomotive is drawn back it will go with it, as indicated in dotted lines in that figure. However, it is to be noted that in the dotted line positionthe blower 15 is missing. This is to show that the inlet 140 can be applied directly to the top of the locomotive stack to direct the gases up in the chimney with out a blower at certain times. It will be understood that the counterweight 145 is heavy enough so that by manipulating the inlet 140 the whole hose may be raised and lowered in the chimney. It is adapted to 'be "applied to a locomotive smoke stack with the blower between whenever the locomotive is approximately under the chimney and no matter how much it is tilted to one side.

In the form shown in Fig. 26, the blower 50' is provided with a weighted ring 150 at the bottom and it is otherwise constructed as shown in the first form of the invention illustrated. Its trunnions are employed to allow it to be picked up by an ordinary crane which can set it around wherever desired on a locomotive. In this case, the locomotivebeing placed under a steam jack as before described, the crane will move around and place the blower on the stack of the locomotive and it will be held there by clips 151 so that it will not be dislodged accidentally. The blower will be connected with the electric supply in any desired way and will discharge the gaseous products of combustion up the smoke jack or chimney. Whenthe o eration is finished, the crane will be employed to move it away. This heavy ring 150 is employed to keep the blower right sideup and to insure its hang-v ing down straight from the crane and furnishes also a limit at the bottom to keep it from sliding about on top of a locomotive smoke stack.

The specific blower mechanism and the modified forms are not claimed herein in detail as they constitute the subject matter of two divisional ap lications.
